Given:
The equation is
[tex]y=21.2x[/tex]
Where, y is earnings for working in dollars and cents and x is the number of working hours.
To find:
The rate of change.
Solution:
The slope intercept form of a linear function is
[tex]y=mx+b[/tex] ...(i)
Where, m is the slope and b is the y-intercept.
We have,
[tex]y=21.2x[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=21.2[/tex]
Therefore, the rate of change is 21.2 dollar and cents per hour.

Answer:
You can
Step-by-step explanation:
To see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them.
Answer:
To tell if a table values are proportional, the x and the y value should have a common factor. When the numbers are all divided by their common factor, the points should all be equal to each other.

A group of friends wants to go to the amusement park. They have no more than $ 100 to spend on parking and admission. Parking is $ 8, and tickets cost $ 23 per person, including tax. Write and solve an inequality which can be used to determine x, the number of people who can go to the amusement park.
Answer:
Step-by-step explanation:
Based on the information given in the question, the inequality which can be used to determine x, the number of people who can go to the amusement park will be:
8 + 23(x) ≤ 100
8 + 23x ≤ 100
23x ≤ 100 - 8
23x ≤ 92
x ≤ 92/23
x ≤ 4
The number of people that can go to the amusement park will be at most 4

Answer:
422.5
Step-by-step explanation:
Given,
Diameter = 23.2
Radius = 23.2 ÷ 2 = 11.6
So, Area is
[tex] = \pi {r}^{2} [/tex]
[tex] = 3.14 \times 11.6 \times 11.6[/tex]
= 422.5184
As rounding to nearest tenth we check the hundreth digit i. e.
422.5184
Since, 1 is smaller than 5 so,
422. 5 (Ans) (Rounded to nearest tenth)

find the height
10cm 8cm
h=
Answer:
h = [tex]\sqrt{84}[/tex] cm
Step-by-step explanation:
The radius, height h and slant height form a right triangle.
radius r = 8 ÷ 2 = 4, hypotenuse = 10
Using Pythagoras' identity in the right triangle
h² + 4² = 10²
h² + 16 = 100 ( subtract 16 from both sides )
h² = 84 ( take the square root of both sides )
h = [tex]\sqrt{84}[/tex] cm
the lablel on a 1/2- pound bag of wildflower seeds states that it will cover an area of 375 square feet . based on this information, what is the number of square feet that 1 pound of wildflower seeds will cover.
Answer: so a 1 and 1/2 bag will cover 375
1=2/2
1 and 1/2=2/2 and 1/2=3/2
so 3/2 pound covers 375
2/2 pounds covers x
3/2pound=375
multiply both sides by 2 to get rid of the fraciton
3pound=750
divide both sides by 3
1pound=250 square feet so the answer is c. 250 square feet

6 cm 8 cm what will be the perimeter and the area of the rectangular below if it is enlarged using factor of 6.5
Answer:
The dimensions of the enlarged rectangle are 6*6.5 cm by 8*6.5 cm, or 39 by 52 cm. The area of this rect. is therefore (39 cm)(52 cm) = 2028 cm^2. The perimeter of the original rectangle is P = 2(6 cm) + 2(8 cm) = 28 cm. The perimeter of the enlarged rectangle is P = 2(39) + 2(48) = 174 cm.

Find the largest perfect square that divides 350584416
The largest perfect square that divides 350584416 is 58430736
The number is given as: 350584416
Express the number as the product of its factors
350584416 = 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3 x 7 x 7 x 7 x 7 x 13 x 13
Express the numbers as exponents
350584416 = 2^5 * 3^3 * 7^4 * 13^2
Rewrite the product as:
350584416 = 2^4 *2 * 3^2 * 3 * 7^4 * 13^2
Reorder the factors
350584416 = 2^4 * 3^2 * 7^4 * 13^2 * 2 * 3
Express the product as a product of a perfect square
350584416 = (2^2 * 3 * 7^2 * 13)^2 * 2 * 3
Write out the perfect square (k)
k = (2^2 * 3 * 7^2 * 13)^2
Evaluate the product
k = (7644)^2
Evaluate the exponent
k = 58430736
Hence, the largest perfect square that divides 350584416 is 58430736

Marking brainiest
Answer:
279 ft²
Step-by-step explanation:
A=bh
A=16x16
A=256
Subtract the area of island
A=bh
A=3x7
A=21
256-21=235
Then you have to find the area of the trapezoid at the top, which is a reactangle and then two smaller triangles
A=bh
A=10x4
A=40
A=1/2bh
A=4x1x1/2
A=2
Multiply it by two because there are 2 of them
2x2=4
40+4=44
The area of the main part is 235 and the area of the side section is 44.
Add them together
235+44=279 ft²

Answer:
The owner makes $2 in sales per customer
Note: The "Amount of sales" label of the question is phrased poorly. s could be better labeled "profit from sales" or at least "Amount made from sales", etc.
Step-by-step explanation:
If you logically think about how the answer (now that you know it) relates to the question, it should make simple sense.
i.e. if you consider the first column where $24 is made from 12 customers, and divide the $24 made by the 12 customers, you'll see that each customer spends $2.
Answer:
the owner makes 2 dollars in sales every week
Step-by-step explanation:
on the chart/graph it shows 6 new customers every week and if you want to see how much more money the owner makes off of each customer then...
subtract the first weeks number of customers from the second weeks to get the answer of 6 new customers per week as you can see on the chart/graph (this really isnt to important though)
then divide the total number of customers for 1 week by the profits made for that week to get an answer of 2 dollars for customers.
